CARRIER FOR PHOTOGRAPHIC PLATES.

Specification of Letters Patent.

Patented Jan. 30, 1906.

Application filed April 1'7, 1905. Serial No. 255,958.

To all whom, it may concern.-

Be it known that I, EDWARD LANDER HALL, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Im proved Carrier for Photographic Plates, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide a receptacle in which photographic plates may be placed and supported on end, the receptacle being adapted to contain liquid, so

that the plates may be transported in a wet condition, enabling them to be subsequently thoroughly washed and preventing the possibility of the hypo drying on the plates and staining them during transportation.

A further purpose of the invention is to provide a display receptacle or carrier for photographic plates, especially adapted for use in the field as an adjunct to a portable dark room, for example, the device being so constructed as to comprise a body adapted to contain liquid and a top capable of being closed in a liquid-tight manner, which top or cover is provided with an inlet and an outlet for the liquid, and a skeleton tray loosely contained in the body and fitted to receive and hold the plates at desired distances apart.

The invention consists in the novel con struction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures.

Figure 1 is a perspective view of the improved device, and Fig. 2 is a longitudinal vertical section through the same.

The body A of the receptacle is preferably made rectangular, as illustrated, being open at the top, but otherwise closed, and at the upper edge or mouth of the body A a contin uous outer marginal flange 10 is produced, having its under edge provided with an undercut and angular groove 11, shown in Fig. 2. The body A contains a tray B, loosely fitted therein, the body 12 of which tray is of skeleton formation, so as to render it as light and as open as possible consistent with strength, and near the top and bottom of the side portions of the body of the tray the conventional corrugated strips 13 are secured, which strips serve to hold the plates suitably spaced in an upright position. For convenience in handling, the tray B is provided with hinged or pivoted handles 1 1 at its ends.

The top or cover C is provided for the body A, removably fitted thereto in a water and air tight manner. This cover C has a downwardly-extending marginal flange 15, which when the cover is in position fits snugly upon the flange 10 of the body A, but terminates short of the lower edge of the body-flange. At intervals, usually at each side and end portion of the cover-flange 15, a vertical tubular offset 16 is made, the bore whereof extends through from end to end. A clamp D is provided for each offset 16, and each clamp consists of a shank-section 17, having its upper end threaded and its lower end formed into an angular or hook-shaped head 19, and a nut, usually a wing-nut 18, adapted to the threaded end of the shank 17. In applying the clamp D, the cover C being in place, the shank 17 is passed up through the bore of the offset 16 until the bill of the hook-head 19 is made to enter the undercut groove in the body flange 10, and finally a nut 18 is screwed upon the shank 17 to a proper engagement with the top of the offset, as shown in Fig. 2.

In order to secure a thoroughly watertight connection between the cover 0 and the body A of the device, a marginal gasket 20 is secured, preferably, in a marginal groove 21 in the under face of the cover, which gasket when the cover is in place engages with the upper edge of the body A, extending transversely from the inner face of the body to the outer face of its flange 10, as is shown in Fig. 2.

The cover C is provided with a handle 22, and preferably near each end of the cover at the top an aperture is made, which apertures are designated as 23 and 24;, one aperture be ing an inlet for liquid and the other an outlet. Each aperture is surrounded by an upwardlyextending threaded collar 25, and a cap 26, having a suitable washer 27, is normally secured to each collar to close the aforesaid apertures 23 and 2 1.

In operation, the cover being removed from the body, the tray is placed in position therein and the body is filled with water. As the plates are developed they may be primarily washed in another vessel and finally washed in the water within the body, the plates being placed in the tray B, and this tray may be moved up and down, if desired, to facilitate said washing. When the desired number of plates have been developed and have been placed in the body A, the cover C is secured to the body in the manner which has been described, and by unscrewing the caps 26 a hose may be attached to the inletaperture 23, for example, and water may be supplied from any suitable source to the in terior of the body, whereupon the water will circulate through the plates and the surplus water will pass off through the outlet 24. WVhen the plates are to be transported, they are permitted to remain in the liquid in the body, and the caps are then secured to place, thoroughly closing the interior of the body. The plates may now be carried to any distant point and if not properly washed at the initial operation can be taken out and washed under more convenient circumstances and the water will have kept the plates moist, preventing any excess of hypo from drying on the plates and staining them, and the fact of carrying the receptacle causes the contents to be agitated and the plates consequently to be subjected to a washing process through that entire period.

This device is particularly adapted for work in the field and for use in connection with a portable dark room or any temporary structure or device wherein plates are developed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent As an improved article of manufacture, a carrier for photographic plates, consisting of a box-like receptacle, a skeleton tray provided with guides for a number of plates, the said tray being independent of the said receptacle but removably contained therein, a

cover for the receptacle, provided with a capped inlet and a capped outlet, and. devices engaging the cover and the receptacle, holding the two connected in a liquid-tight manner.

2. A carrier for photographic plates, consisting of a receptacle open at the top but otherwise closed, a skeleton traylocated within the said receptacle, a cover fitted to the top of the receptacle in a water-tight manner, clamps carried by the cover and engaging with the receptacle, the said cover being provided with an inlet and an outlet aperture, and removable covers for the said apertures.

3. In a carrier for photographic plates, a receptacle open at the top but otherwise closed and provided at its upper portion with an exterior marginal flange having an undercut groove in its lower edge, a skeleton tray located within the receptacle, a cover for the said receptacle, provided with a downwardlyextending marginal flange adapted for en gagement with the body-flange, tubular oil"- sets from the said cover-flange, clamps carried by said o'l'lsets, each clamp comprising a threaded shank passed through a bore of an offset and provided with a nut at its threaded end, and a hook-head the bill whereof is adapted to enter the groove in the body flange, the said cover being provided with an inlet and an outlet aperture, a threaded collar around each aperture and caps adapted to be screwed upon. said collars.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EDWARD LANDER HALL.
